WebA K v value is defined as the rate of flow of water in m 3 /hr and 4°C at a pressure drop of 1 bar across the equipment. K v relates to pressure drop and flow rate via the following expression: \displaystyle K_v = Q \sqrt { … WebCv = Flow coefficient [GPM/PSI1/2] The flow coefficient Cv is the necessary proportionality constant, and it is typically determined experimentally. Usually, flow …
WebFor that purpose resistance coefficient K, equivalent length L/D and flow coefficient Cv, Kv are used. These values are available from different sources like tables and diagrams from different authors and from valves manufacturers as well.
